Application filed August 29, 1922. Serial No. 585,083.

To all whom it may concemi Be it known that 1, CHARLES R. CAMERON, asubject of the King of Great Britain, and residing at Los Angeles, inthe county of 5 Los Angeles and State of California, ave invented newand useful Improvements in Indicating Means, of which the following isa' specification.

This invention relates to indicating means which may be utilized forvarious purposes, such as determining from a direction rearwardlv of ahead light whether or not said head light is burning. The device may beutilized in conjunction with railway switch lanterns and the like, or itmay be utilized in conjunction with motor vehicles. The device inparticular will indicate the exact c0ndition of the light, as well aswhether or not the same is burning.

In practicin the invention I provide a device which inc udes a casinghaving a light or vision-transmitting part and a receiving part, wherebythe general appearance of a lamp within a head light or other device 2may be viewed as to its general appearance at the receiving part, and inaddition the intensity of its burning may likewise be determined.

With the above and other objects in View,

the invention consists inthe novel and useful provision, formation,construction and relative arrangement of the parts, members and featuresasdisclosed in the drawing, described in the following statement andfinally pointed out in claim.

In the drawing:

Figure 1 is a cross sectional view of a head light incorporating theindicating means;

Figure 2 is a view similar to Figure 1,

4 showing a modified form of indicating means; and

Figure 3 is a perspective view of the indicating means shown in Figure1.

Corresponding'parts in all the figures are designated by the samereference characters- Referring with particularity to the drawing, Adesignates in its entirety the indicating vmeans of Figures 1 and 3, andB the indicating means shown in Figure 2, which indicating means, eitherA or B, is utilized in the embodiment shown in combination with a headlight C, which head lightmay1 include the usual outer casing 1 formedwit a part 2 adapted to receive a retaining ring 5 3 adapted to hold alens a to said casing 1,

with a reflector 5 within said casin 1 and a source of light 6 normallylace at the focal point of said reflector. t is intended that the deviceA or B should receive a cer tain portion of the light rays emitted bythe lamp 6 and transmit a reflection of said rays in a directionrearwardly of the head light casing 1. It the head light is used on amotor vehicle it may be easily determined by the driver of the vehiclewhether or not 05 the lamp 6 is burning, and likewise to observe thelamp 6 in the case of the device shown by A. The devices A and Bare inreality attachments which may be fitted to any form of lantern or thelike. The indicating means A may include a casing 11 of three parts, 7,8 and 9, the parts 7 and 9 being angularly disposed with relation to thepart 8. In the showing the casing a is rectangular in cross section. Thepart; 7 flares outwardly as shown at 10, and is adapted to receive andmaintain in position a translucent member .11, said translucent memberclosing the mouth of the part 7, as shown at 12. The flared part 10 isprovided with a flange 13, so which maintains the translucent member 11in position. In particular the translucent member 11 may be curved, asshown in Figure 3, so as to ive a wide field of vision. The mouth 14. othe part 9 is open and any light rays passing through the mouth ld intothe art 9 will be reflected by means of a sma reflector 15 set at anangle as between the parts 8 and 9, to a mcond reflector 16 set at ,anan le with relation to the parts 7 and 8, an from thence the reflectorprojects the light re s to the translucent member 11. if desired t etranslucent member 11 may be formed of ground glass, and hence the lam 6would appear in miniature upon sai ground glass, and its generalappearance readily determined. By curving the translucent member 11 itis possible to view the lamp 6, as well as determine whether or not itis burning, from numerous positions, it not being necessary to observesaid translucent member from one osition. The' casing a may be providedwit .a clip memher I) which will coo crate with the ring 3 and thecasing 1 for olding the casing'a in 1 position. In articular, the clip'5 includes a part as 17 oined with the part 8 of the casing a with anexded part 18 having its end bent in the form of a letter S forming theparts 19 and 20. in assembling the indicating means A to the head lightC, the retaining ring 3 is removed, whereupon the part 2 of the casing 1is received between the members 19 and 20 of the clip I) and theretaining ring then slipped between the parts 18 and 19 of the clip 6and the retaining ring 3 then placed upon the member 2 of the casing 1.This will securely hold the indicating means A in position. The part 8of the indicating means is of suflicient length that the lighttransmitting part is in contact with the lens 4, as best illustrated inFigure 1, and with the light receiving part above the casing.

The modification shown in Fi re 2 consists in providing a casing 0having the clip member 5 joined thereto, with said casing 0 closed atits upper end, as 21, and open at its lower end, as shown at 22, therebeing an opening 23 in a portion of said casing, with alight receivingmember 24 which may be formed of glass or other translucent substancewithin said casing. One end of said 7 light-receiving member, as 25,projects below the open mouth of the casing, While the other end may beformed with a bead 26 projecting through the opening 23 in the casing.As stated, this device is held in position upon the head light in asimilar manner to that 'ust described for the indicating means A. hislatter device B will function similar to the device A, with theexception that the device B will not visualize the lamp 6, but simplyabsorb light from the said lamp and glow.

It is obvious that the clip member I) might be bent in a variety offorms and shapes to adapt the same for use and service with variousdevices, and that the said indicating means may be changed in variousrespects in departure from the showing, without departing from the truespirit of the invention and the scope of the appended claim.

Having thus disclosed m invention, I claim and desire to secure byetters Patent:

The combination, with a head light having the usual casing, lens member,retaining ring for holdin the lens to the casing, and lamp within saidhead light, of means adapted for placement in front of the lens memberfor receiving rays of light from the lamp and projecting a portion ofsaid rays in a direction rearwardly of the head light; said means beingprovided with a member adapted to be locked between the casing andretaining rin for maintainin said means in position re ative to the helight.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES R. CAMERON.
